Actually, looking at the code, it doesn't necessarily mean your CPU is too 
slow, just that your XFree86 driver and/or your graphic card doesn't support 
double buffering.

It's not surprising you get this... AFAIK most XFree86 drivers don't support 
double buffering yet (neither my desktop nor my laptop do).

I would bet that it is trying to perform an update rects or blit rect or 
something outside of the screen's boundaries (we used to have these things 
all the time in Tux Typing, untill I added in checking code to ensure that we 
didn't blit outside the window ;-)

Can you place your code online somewhere (I think you still have Noink access 
on my site, so you could use that if you wanted) so we can look at it?
